### Getting Started with API

The Ant-A3 SDK has primary classes: `TradeHub`.  
- **TradeHub Class**: This class handles direct interactions with the Ant-A3 API, including managing sessions, placing orders, and retrieving market data.

#### Session Management
The `get_session_id` method is used to retrieve a session ID from the Ant-A3 server. The session ID remains valid until you log out of your trading account. It is recommended to generate the session ID once during login and store it securely for subsequent use. 

#### 1. Import the Library
Import the required class from the SDK:
```python
from TradeMaster.TradeSync import *
```

#### 2. Create a Trading Object
Initialize a Trading object using your user_id, auth_code, and secret_key
```python
trade = TradeHub(user_id="YOUR_USER_ID", auth_code="YOUR_AUTH_CODE", secret_key="YOUR_SECRET_KEY")
```

#### 3. Get Session
To get the session ID, use the get_session_id() method.

You can call it directly, or optionally provide a check_sum or an existing session_id if you already have them.
```python
# Get session ID (default way)
print(trade.get_session_id())

# Optionally, pass a checksum if you have one
print(trade.get_session_id(check_sum="your_checksum_here"))

# Optionally, pass an existing session ID
print(trade.get_session_id(session_id="your_existing_session_id"))
```

#### 4. Download the contract master
Master contracts simplify the process of locating instruments by their symbol names and placing orders. These contracts are stored locally as CSV files, organized by token number and symbol name.
By default, master contracts for all enabled exchanges in your profile are downloaded.
To download contracts for specific enabled exchanges (e.g., ['NSE', 'BSE', 'NFO', 'BFO', 'CDS', 'BCD', 'NCO', 'BCO', 'MCX', 'INDICES', 'NCDEX']), replace "EXCHANGE" with the desired exchange names in the command below:
```python
trade.get_contract_master(exchange="EXCHANGE")
```

#### 5. Retrieve Available Instruments for Trading
Instruments can be fetched based on their symbol, token, or Futures & Options (FNO) from the downloaded contract master as shown below:
```python
# Fetching instrument by symbol (TCS) or trading symbol (TCS-EQ) for all exchange
print(trade.get_instrument(exchange=Exchange.NSE, symbol='TCS'))

# Fetching instrument by token for all exchange
print(trade.get_instrument(exchange=Exchange.NSE, token='11915'))

# Fetching Futures & Options instrument
print(trade.get_instrument_for_fno(exchange=Exchange.NFO, symbol='HAL', expiry_date='2025-04-24', strike='5000',
                                               is_fut=False, is_CE=True))
```

### Order & Trade Management

#### Place Order
To place an order, use the trade.placeOrder() method. You can provide the instrument details in one of three optional ways:
   - Option 1: Using instrumentId, exchange (When you already know the token (instrumentId) and exchange, pass both directly.)
   - Option 2: Using get_instrument (When you only know the symbol, this function will fetch the instrument; no need to pass the exchange separately.)
   - Option 3: Using get_instrument_for_fno (for Futures & Options, when you know the symbol details; no need to pass the exchange separately.)

Option 1:
```python
placeOrder = trade.placeOrder(instrumentId='532822', 
                              exchange=Exchange.BSE,
                              transactionType=TransactionType.Buy,
                              quantity='2',
                              orderComplexity=OrderComplexity.Regular,
                              product=ProductType.BNPL,
                              orderType=OrderType.Market,
                              price='',

### GTT Order & Trade Management

#### GTT Place Order
To place an GTT order, use the trade.GTT_placeOrder() method. You can provide the instrument details in one of three optional ways:
   - Option 1: Using instrumentId, exchange (When you already know the token (instrumentId) and exchange, pass both directly.)
   - Option 2: Using get_instrument (When you only know the symbol, this function will fetch the instrument; no need to pass the exchange separately.)
   - Option 3: Using get_instrument_for_fno (for Futures & Options, when you know the symbol details; no need to pass the exchange separately.)

Option 1:
```python
GTT_placeOrder = trade.GTT_placeOrder(instrument=trade.get_instrument(exchange=Exchange.MCX, token='460125'),
                                      transactionType=TransactionType.Sell,
                                      quantity='30',
                                      orderComplexity=OrderComplexity.Regular,
                                      product=ProductType.Intraday,
                                      orderType=OrderType.Limit,
                                      price='100',
                                      gttValue='10',
                                      validity=PositionType.posDAY)

print("User GTT_placeOrder :", GTT_placeOrder)
```

Option 2:
```python
GTT_placeOrder = trade.GTT_placeOrder(instrument=trade.get_instrument(exchange=Exchange.NSE, symbol="HFCL"),
                                      transactionType=TransactionType.Sell,
                                      quantity='30',
                                      orderComplexity=OrderComplexity.Regular,
                                      product=ProductType.Intraday,
                                      orderType=OrderType.Limit,
                                      price='100',
                                      gttValue='10',
                                      validity=PositionType.posDAY)

print("User GTT_placeOrder :", GTT_placeOrder)
```

Option 3:
```python
placeOrder = trade.placeOrder(instrument=trade.get_instrument_for_fno(exchange=Exchange.NFO, symbol='HAL', 
                                                                                    expiry_date="2025-05-29", 
                                                                                    strike="35366", is_fut=False, is_CE=True), 
                                      transactionType=TransactionType.Sell,
                                      quantity='30',
                                      orderComplexity=OrderComplexity.Regular,
                                      product=ProductType.Intraday,
                                      orderType=OrderType.Limit,
                                      price='100',
                                      gttValue='10',
                                      validity=PositionType.posDAY)

print("User GTT_placeOrder :", GTT_placeOrder)
```

#### Modify Order
To place an GTT Modify order, use the trade.GTT_modifyOrder() method. You can provide the instrument details in one of three optional ways:
   - Option 1: Using instrumentId, exchange (When you already know the token (instrumentId) and exchange, pass both directly.)
   - Option 2: Using get_instrument (When you only know the symbol, this function will fetch the instrument; no need to pass the exchange separately.)
   - Option 3: Using get_instrument_for_fno (for Futures & Options, when you know the symbol details; no need to pass the exchange separately.)

Option 1:
```python
GTT_modifyOrder = trade.GTT_modifyOrder(brokerOrderId="25071400010780",
                              instrument=trade.get_instrument(exchange=Exchange.MCX, token='460125'),
                              quantity='30',
                              orderComplexity=OrderComplexity.Regular,
                              product=ProductType.Intraday,
                              orderType=OrderType.Limit,
                              price='100',
                              gttValue='10',
                              validity=PositionType.posDAY)

print("User GTT_modifyOrder :", GTT_modifyOrder)
```

Option 2:
```python
GTT_modifyOrder = trade.GTT_modifyOrder(brokerOrderId="25071400010780",
                              instrument=trade.get_instrument(exchange=Exchange.NSE, symbol="HFCL"),
                              quantity='30',
                              orderComplexity=OrderComplexity.Regular,

                              gttValue='10',
                              validity=PositionType.posDAY)

print("User GTT_modifyOrder :", GTT_modifyOrder)
```

Option 3:
```python
GTT_modifyOrder = trade.GTT_modifyOrder(brokerOrderId="25071400010780",
                              instrument=trade.get_instrument_for_fno(exchange=Exchange.MCX, symbol='IDEA', 
                                                                      expiry_date="2025-04-29",

                              validity=PositionType.posDAY)

print("User GTT_modifyOrder :", GTT_modifyOrder)
```

#### GTT Cancel Order
To GTT cancel a previously placed order, use the GTT_cancelOrder() method by providing the brokerOrderId (Order Number).
```python
# Example: Cancel an order by Order Number
print(trade.GTT_cancelOrder(brokerOrderId='25071400010780'))

### General instruction

### Order Validation Logic

#### Order Type As (Limit or SL)
- `price` must be greater than zero.

#### Order Type As (SL or SLM)
- `slTriggerPrice` must be greater than zero.

#### Order Type As (SL) and Order Complexity As (BO, CO)
- `slLegPrice` must be greater than zero.

#### Order Complexity As (BO)
- `targetLegPrice` must be greater than zero.

### Read this before creating an issue
Before creating an issue in this library, please follow the following steps.

1. Search the problem you are facing is already asked by someone else. There might be some issues already there, either solved/unsolved related to your problem. Go to [issues](https://github.com/jerokpradeep/pya3/issues)
2. If you feel your problem is not asked by anyone or no issues are related to your problem, then create a new issue.
3. Describe your problem in detail while creating the issue. If you don't have time to detail/describe the problem you are facing, assume that I also won't be having time to respond to your problem.
4. Post a sample code of the problem you are facing. If I copy paste the code directly from issue, I should be able to reproduce the problem you are facing.
5. Before posting the sample code, test your sample code yourself once. Only sample code should be tested, no other addition should be there while you are testing.
6. Have some print() function calls to display the values of some variables related to your problem.
7. Post the results of print() functions also in the issue.
8. Use the insert code feature of github to inset code and print outputs, so that the code is displayed neat. ![image](https://user-images.githubusercontent.com/38440742/85207234-4dc96f80-b2f5-11ea-990c-df013dd69cf2.png)
9. If you have multiple lines of code, use triple grave accent ( ``` ) to insert multiple lines of code. [Example:](https://docs.github.com/en/github/writing-on-github/creating-and-highlighting-code-blocks) ![image](https://user-images.githubusercontent.com/38440742/89105781-343a3e00-d3f2-11ea-9f86-92dda88aa5bf.png)
